TRANSFER MECHANISM.

Specification of Letters Patent.-

Patented May 11, 1909.

Application filed April 7, 1908. Serial No. 425,728.

To all whom it may concern: 6

Be it known that I, Vro'ron Ross, of Duquesne, Allegheny county,Pennsylvania, have invented a new and useful Improvement in TransferMechanism, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a plan view showing aroller feed table and hot-bed equipped with my im roved apparatus; Fig.2 1s a sectional en elevation of the same on the line 11-11 of Fig. 1;Fig. 3 is a sectional side elevation on the line III-III of Fig. 1; Fig.4 is a de} tail plan view; and Fig. 5 is a sectional sid'e ing apronplates, forming part of my invention, the apron plate being shown indotted lines in its extreme tilted positions, in Fig. 5.

My invention relates to apparatus employed in handling the products ofrolling mills, such as round, flat and square metal bars, or rails,beams, tubes, pipes and other rolled shapes, and the invention moreparticularly relates to the handling of such material'in delivering themfrom the forming rolls during the rolling operation or after the rollingoperation has been completed, to feed tables or to the hot-bed or otherplace of storage.

The object of the invention is to 1provide a simple and effectivemechanism y which the bars or other materials are delivered, transferredor removed from the rollers of. a feed table transversely to the line offeed of the feed table to a arallel feed table or to the skids forming aot-bed or storage bed.

In the drawings, 2 represents the rollers of a feed table which islocated in front of and in line with the pass of a rolling mill or otherpoint of su Iply forthe bars or other articles to be hand ed. A hot-bedor storage bed formed by the skids 3 and 4 is located on each side ofthe feed table. Instead of having a storage bed on each side of the feedtable, as shown in the drawings, but one such bed may be used, which canbe located on either side of the feed table, as is desired. The rollers2 are positively driven through bevel'gears 5 and 6', and the line shaft7 by means of any desired type of motor (not shown) in the usual manner.

Located between the feed rollers 2 are tilting apron plates 8, which arepivotally mounted on the sides 9 of the feed table, the

pivot shafts 10 extending transversely across the width of the feedtable with their axes parallel to the axes of the rollers 2. The apronplates 8 are preferably provided on two edges with side guards 11, whichextend in lines parallel with'the sides 9 of the feed table and projectupwardly above the top face of the apron plates and above the level ofthe top ofthe rollers 2, to keep the materials in osition on the rollers2 of the feed table wl ile being fed forwardly len thwise on the table.The other edges 12 an 12 of the apron plates 8 are formed at an angle tothe axes of the pivot shaft on the' apron piate and as shown, theseedges are parallel. stead of forming both edges 12 and 12 on an angle tothe pivotal axis of the apron plate, but one edge may be at such anangle, or the edges 12 12 may be at relatively o posite angles to theaxis of the ivot sha This latter construction may be ound desirablewhere the hot-bed or feed table is located on one side only of theroller table, and by such construction the metal may be transferredsidewise from the rollers by tilting the apron plates in eitherdirection. 1

Each of the apron plates 8 is provided with a depending arm 13 which, asshown, is forked at its outer or lower end so as to embrace the ends ofthe links 14 by which the arms 13 are connected together. At theopposite ends of the feed table are fluidactuated cylinders 15, 16, eachof which is provided with a plunger 17, and cross-heads 18, and thecross-heads 18 are connected by links 19 with the links 14 which connecttogether the arms 13 on the apron plates 8. In the operation of myimproved transfer mechanism, the bars or other materials are fedforwardly on the rollers 2, of the feed table, until they are oppositethe storage bed or the feed tables in os1t1on to be transferred sidewisefrom the ro lers 2 to the skids or the feed tables. One of the cylinders15 is then actuated by means of a suitable fiuidressure supply, and theplunger 17, throng the links 19, 14, and arms 13, rocks or tilts theseries of apron plates 8 into one or the other of the positions shown bydotted lines in Fig. 5. As the apron plates are rocked, the beveled orangular edge 12 on these plates lifts the metal from the rollers andwhen the angle of the edges .12 reaches the angle of I claim:

repose of the materials being lifted, these materials are caused toslide transversely from the table on to the skids 3, forming thehot-bed, or to the feed table, when such are used. It will be noted byreference to Fig. 5, that the top edge of the side guards 11 areinclined in such manner as to be clear of the when the a ron plates arein their tilted position to shi t the bars transversely from the rollertable to the skids forming the hot-bed or to the feed tables.

The apron plates are thenmoved by means of the cyhnders 15, 16, andconnecting mechanism, into a horizontal position in readiness toreceiveand guide the next bar or bars while being delivered by therollers 2. When one bedhas been filled with material the apron platesare then tilted in the opposite dlrection to transfer the materials tothe hot-bed located on the o posite side of the roller table. Insteadof, iiist filling one hotbed with material and then filling the hotbedon the opposite side of the feed table, while the material on the firstfilled bed is being removed, the apron plates may be tilted inalternately opposite directions, so

as to gradually fill botn beds at the same ,ing material feed table to ahot-bed,

time. The bars or other articles may be transferred singly from the thea ron plates or a lurality of bars may be collected on the r0 er tablebetween the operations of tilting the apron plates when such latteroperation is found desirable.

The advantages of my invention are many and will be apparent to thoseskilled in the art. The apparatus is sim 1e and is easily kept inrepair. Instead o tioiiary apron plates and side guards with theseparate mde endent mechanism for removrom the feed table, the a ronlates are arranged to be rocked or tilte and h the tilting operation toautomatically transfer the material from the feed table to the stora eor hot beds, located on each side of the roIler feed table.

While the tilting apron plates are shown arranged to transfer materialsfrom a roller obviously the apparatus can be used in transferringmaterials transversely from one roller feed table to another.

Variations in the construction and arrangement of the apparatus may bemade without departin from my invention. The side guards may e se arateand stationary instead of (as shown) being formed integral with the aron plates. Insome cases, the rollers of t e feed table may be dispensedwith and other means provided for feeding materials forwardly on theapron plates, into position to be transferred transversely by the tiltinapron plates and other modifications mayie made Within the scope of myinvention.
